You are probably asking, what is “fallow syndrome” and why should I care? After all, summer fallow is not that common anymore! But the greater number of Prevented Planting acres in 2019 and […]
Field Variability Screaming in Your Ear? Precision Soil Sampling is the Answer
in Precision Ag/by Jodi BoeYour land is variable. Each fall, you watch the combine yield monitor go up and down across the field. You know where crop yield will be the best in wet years and dry years. So, why do you still use a whole-field composite soil test to manage fertilizer inputs and ignore the obvious field variability […]
Prevented Planting Acres in 2020: Maximizing Cover Crop Effectiveness
in Cover Crop, Prevented Planting, Soil Erosion, Soil Health, Tillage, Water Quality, Weed/by John BrekerIn 2020, there are again widespread acres of Prevented Planting (PP) in North Dakota and northwest Minnesota. Farmers are now making plans to plant cover crops on unplanted cropland in the next few weeks. It is important to establish cover crops on PP fields because growing plants help reduce the chance these fields will be […]

When a drought occurs, it is normal to find higher residual soil nitrate-nitrogen after harvest. Since the widespread adoption of soil testing in the 1970s, we have seen this phenomenon in all major drought years: 1988, 2002, […]
